Re: RCA 32V420T 32" TV

This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.

I have a RCA 32V432T 36in...the screen is light blue with white horizontal looks like a film in front of the actual picture...there is still audio though. what's going on?

There are two main causes for this fault. The first one is, advanced screen voltage to the screen grid of picture tube. The second one is leaky blue video output transisotr.
Just open your TV, and locate the screen control. It usually can be located with LOT [Line Output Transformer]. There will be two adjustable controls integrated to this LOT, marked as screen and focus. Out of which, the lower one will be for screen adjustment, and the upper one for focus adjustment. Just rotate the screen control [the lower one] to a little counterclockwise, so that the thin horoizontal lines on the screen just fade of. Adjustment is critical and should be done with care, and a small movement may just be enough. If it does not help you, repalce the blue video output transistor. This part can be located at the bace card [the printed circuit board fitted to the neck of the picture tube]. Locate it, replace it. OK.

IHVT or flyback transformer has 3 leads = high voltage to CRT,
focus and screen leads to small circuit board on end of CRT.

Horizonal line

I think you have a fault on the picture frame board. If you can check for this yourself or find a competant technician. Hope this helps.
